Eric,

You may be talking about Bagster/Moulton 1977 and if so Pierre Guillemette*
gives a detailed explanation of how it was revised and how many more
revisions would be required to bring it into line with NA26. Guillemette's
work was based on the computerized concordance of NA26 and it may have been
the first of its kind in this respect. At least that is what he seems to be
claiming in the intro to his book.
